WEIGHT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 660,011, dated October 16, 1900. Application filed May 14, 1900. Serial No. 16,645. (No model.)

To all whom, it may concern:

Be it known that LU'J. FUHRMAN, a citizen of the United States, residing at tVest Salem, in the county of TVayne and State of Ohio, have invented a new and useful Weight-Motor, of which the following is a specification.

My present invention relates to a novel weight-n1ot0r for the generation of power designed to be transmitted to pumping or other transforming mechanisms.

The objects in view are to so construct and arrange the cooperating parts of the motor as to obtain a maximum efficiency of applied force with a minimum expenditure of initial energy and, further, to embody in a motor a driven or power-transmitting element having an oscillatory movement and related to the rotary power or driving element in a manner to overcome in a large measure the tendency of such cooperating parts to bind when the direction of pressure exerted by the rotary element is in a practically direct line with the resistance opposed by the driven or transmitting element.

To these ends and to others subordinate thereto the invention consists in the construction and arrangement of parts hereinafter fully described, and succinctly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of my apparatus complete equipped for use as a pump-motor. Fig. 2 is a sectional View, on a somewhat-enlarged scale, showing the relations of the elements of the motor proper, one position of the oscillatory transmitter being shown in dotted lines. Fig. 3 is a view illustrating the subject-matter of Fig. 2 viewed from the opposite side of the gearing, and Fig. 4L is-a detail View of the tackle-block and guard for the winding-cable. Fig. 5 is a detail view of the angle-sleeve and connected parts.

Referring to the numerals of reference employed to designate corresponding parts in each of the several views, 1 indicates a base or platform designed to sn pport my apparatus and having bolted or otherwise secured thereon a stand 2 of a pump 3, whose suction or supply tube 1 is extended below the platform 1 for the purpose of placing the pump in connection with a source of water-supply. The

frame or superstructure designed for the sup port of the motor at a point above the pump may be constructed in any suitable manner; but I prefer that the frame should be composed of the parallel slightly-inclined standards 5, connected at their upper ends and at a point above the pump by a head-beam and transverse bar, (indicated, respectively, by the numerals 6 and 7.) From the center of the head-beam extends rearwardly a head beam extension 8, to the rear extremity of which is hinged the upper end of an inclined brace 9, resting at its lower end upon the platform 1 or upon suitable step blocks carried thereby, the relative inclinations of the standards and brace serving to form a comparatively-broad supporting-base for the motor frame or superstructure.

At a suitable point above the standards, preferably some little distance above the pump, I provide opposed bearing-brackets 10, in which are journaled the opposite ends of what may be termed the cable or drum shaft 11, upon which is keyed adjacent to one end the winding-drum 12 for the reception of the winding or resetting cable 13, which is passed upwardly and over the sheave 14 of a tackle-block 15, suspended from the under side of the head-beam 6, The extremity of the winding-cable depends to within convenient reach of an operator stationed upon the platform 1 and is provided with a handle or button 16, designed to be grasped by the op erator for the purpose of exerting a pull upon the winding-cable to unwind the latter from the drum 12. The unwinding of the cable 13 from the drum 12 effects the winding of the power or weight cable 17, which is wound upon the shaft 11 in a direction the reverse of the winding of the cable 13 upon the drum. The weight-cable 17 is carried upwardly from the shaft 11 and is carried over the sheave 18 of a pulley-block suspended from the head-beam extension 8 at a point which will cause the weight 19, attached to the lower end of the power-cable, to move in a vertical plane located midway between the standards and brace. This relation of the weight to the frame is desirable, as the weight is thus distributed equally upon the several supporting elements of the frame, but it is not essential, since the weight might be located in any suitable position, so loug as its gravitation would termediate of the ratchet wheel or disk 20 and the cable guard-wheel 23, fixedupon th'e shaft and designed to prevent the weighteable when wound upon thesh'aft from in; terfering with the operation of the gearing? The gear-wheel 22 meshes with a.,pini,on,;24, mounted upon a crank-shaft 25, journaled in suitable bearings 26, located justbelow the i pen the crank-shaft, iwhichl will hereinafter denominatethef drive ling?"shaft orelem-ent, alsolreyed a.,gear} 20 wheel 27, meshing with a, pinion 28,.keyed upon a short shaft 29, which carrie s flywheel 30, designed to render the operationoi" themotor uniform and toov'ercomebyjts im petus the tendencyof the elements to stalk. At a suitable point, below the drive-shaft, preferably upon the transversebar 7f, .Ifmount a pair of bearing-hrackets 3lfor the reception of a rock-shaft 32, which passesthrengh an angle-sleeve 33 and is retained in rigid-relation to the shaft by a setscrew34. The sleeve 33 is designed for theretentionupon,theshaft of the balance or pump lever 35 ,provided;at one extremity with an adj u stable ceunterpoise 36 a d at i Qppw' een wi h an. a

for the reception ofthelower extremities of a t wisted loop 41, extending upwardly from the rock-shaft and within which moy es the i It W ll, e served that the elongated twisted lo op 4:1 is

so formed topermit the wrist of the driving- Y shaft to pass therethrough andto permitithe lower ends of the loop, which are threaded, to pass through the apertures 40, which are correspondingly threaded and which retain the endsof ,theloop in such close proximity to the opposite endso f the sleeve 33thatflthe latter is retained against lateral rnove nent 7 upon the rook-shaft in the eventro f its'fsetscrew becoming accidentallydisengaged.

This guardx retains the winding- Cable, in contact with a considerable portion-of the periphery of the sheave 14 and is designed to hold the winding-cable taut as it is drawn through the block by the rotation of the drum under the .influ-encegof the descending weight.

The operation of my device is as follows: Assuming the apparatus to be organized as represented in Fig. 1 of the drawings, the descent of the weight will cause the rotation Of th6 dI lllIl-Sl1?l.fl3 in the direction indicated by the arrow, which will unwind the weight- ,icable-l'i fromtheshaft and will wind the winding or resetting cable 13 upon the drum. The teeth of the ratchetwheel 20 will engage the 2 1 and vbeing in, thisrma nner connected to the gear-wheel 22 will operate the trainof ,lgea rs. and will, rotate the driving-shaft 27. V lfhennove nent of the wrist 42,,moving as it ,doesin acircularipath, will oscillate the loop Ztl,whi ch being rigid withthe rock-shaft32 will rockthe latterfiand causeth e vibration or oscillation of thebalance or pump lever 35,which by reason of its connection with the pitman 3'1 will reciprocate {the ,pump piston, the
